Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle-mounted electronic equipment fixing technology, specifically relating to a vehicle-mounted ETC card fixing device that is easy to install quickly. Background Technology
[0002] Electronic Toll Collection (ETC) technology originated in the 1980s, initially applied on highways in Europe and North America to address the inefficiencies and severe congestion associated with traditional manual toll collection. Early ETC systems primarily used microwave radio frequency identification (RFID) technology, achieving automatic toll deduction through wireless communication between onboard units and roadside units. With technological advancements, ETC systems have evolved towards multi-lane free-flowing, high-precision positioning, and intelligent payment, and are widely used in highways, urban parking lots, gas stations, and other scenarios. Modern ETC not only supports automatic vehicle identification and rapid passage but also integrates with vehicle-to-everything (V2X) and intelligent transportation systems to achieve more efficient traffic management and payment services.
[0003] Traditional adhesive fixing methods use strong adhesive, which makes it difficult to adjust the position after installation and leaves adhesive residue when removing the device. Magnetic fixing is easy to disassemble, but it is prone to displacement or even falling off under the vibration of a vehicle in motion. Ordinary suction cup fixing devices are greatly affected by temperature changes, and the suction force may weaken, causing the device to fall off. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0024] Example
[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a vehicle-mounted ETC card fixing device that is easy to install quickly, including,
[0026] The bottom shell 101, the sliding plate 102 slidably connected to the inner wall of the bottom shell 101, the spring 103 fixedly connected to the surface of the sliding plate 102, the fixing piece 104 fixedly connected to the side wall of the bottom shell 101, the connector 105 fixedly installed at the bottom of the bottom shell 101, the connecting component 106 provided on the surface of the connector 105, and the adsorption component 107 provided on the surface of the connecting component 106.
[0027] Specifically, the connecting assembly 106 includes a connecting plate 106a connected to the surface of the connector 105 by a cylindrical bearing, and a bottom cylinder 106b fixedly installed on the side wall of the connecting plate 106a. The connecting assembly 106 also includes a fixing rod 106c fixedly installed on the inner wall of the bottom cylinder 106b, and a piston 106d fixedly installed on the end of the fixing rod 106c. The connecting assembly 106 also includes a limiting ring 106e fixedly connected to the inner wall of the bottom cylinder 106b, and a pressure relief valve 106f communicating with the surface of the bottom cylinder 106b.
[0028] Furthermore, the bottom cylinder 106b is equipped with two pressure relief valves 106f, which facilitates the quick disassembly of the device and ensures the flexibility of the device during use.
[0029] Preferably, the adsorption assembly 107 includes a movable ring 107a slidably connected to the inner surface of the bottom cylinder 106b, and a connecting cylinder 107b fixedly connected to the side wall of the movable ring 107a. The connecting assembly 106 also includes a sealing plate 107c fixedly connected to the end of the connecting cylinder 107b, and a through hole 107d starting on the surface of the sealing plate 107c. The connecting assembly 106 also includes a suction cup 107e fixedly connected to the surface of the sealing plate 107c, and a top spring 107f fixedly connected to the side wall of the sealing plate 107c.
[0030] It should be noted that the bottom of the suction cup 107e is also provided with a through hole 107d, through which the suction cup 107e is connected to the connecting cylinder 107b, ensuring the convenience of the device when adsorbing glass.
[0031] In use, the ETC card is inserted into the bottom shell 101. The card pushes against the sliding plate 102. The sliding plate 102, in conjunction with the spring 103 and the fixing plate 104, presses the suction cup 107e against the glass. The bottom shell 101 is then pressed down, and the bottom shell 101 moves the connecting plate 106a via the connector 105. The connecting plate 106a moves the bottom cylinder 106b toward the suction cup 107e. The bottom cylinder 106b moves the fixing rod 106c and the piston 106d, expelling the air from the bottom cylinder 106b into the connecting cylinder 107b. The connecting cylinder 107b mates with the through hole 10. Air is expelled from 7d and suction cup 107e, releasing the device. Top spring 107f pushes piston 106d, which drives fixed rod 106c and top cylinder to move away from suction cup 107e. Bottom cylinder 106b, in conjunction with the connection of moving ring 107a and connecting cylinder 107b, generates negative pressure in bottom cylinder 106b. This negative pressure adheres suction cup 107e to the windshield. When removing the device, pressure relief valve 106f is activated, allowing air to enter bottom cylinder 106b through pressure relief valve 106f, eliminating the negative pressure and thus removing suction cup 107e.
[0032] In summary, the adsorption and connection component 106 enables the rapid installation and disassembly of ETC devices. The sliding cooperation between the bottom shell 101 and the sliding plate 102, combined with the buffer mechanism of the spring 103, can stably clamp ETC cards of different thicknesses. The linkage structure of the double bottom cylinder 106b and the piston 106d in the connection component 106, together with the pressure relief valve 106f, can not only form a strong negative pressure adsorption by expelling air when pressed, but also instantly release the vacuum state when the pressure relief valve 106f is operated, which greatly improves the loading and unloading efficiency. The adsorption component 107, through the cooperation of the moving ring 107a, the connecting cylinder 107b and the through hole 107d, enables the suction cup 107e to automatically form a uniform negative pressure distribution when the top spring 107f resets, ensuring a tight fit with the windshield. The device has a compact overall structure and is easy to operate. It solves the problem of difficulty in adjusting the position after installation of traditional adhesive ETC and avoids the defect of easy loosening of magnetic fixation. It is especially suitable for use scenarios that require frequent vehicle replacement or windshield cleaning, and has high practicality and promotion value.
